Upper bound on in a strongly coupled electron-boson superconductor
Nikolay V. Gnezdilov, Rufus Boyack
Migdal-Eliashberg theory of boson-mediated superconductivity contains a divergence in the critical temperature for strong electron-boson coupling . In the convent…
Energy dynamics, information and heat flow in quenched cooling and the crossover from quantum to classical thermodynamics
V. Ohanesjan, Y. Cheipesh, N. V. Gnezdilov +2
The dynamics when a hot many-body quantum system is brought into instantaneous contact with a cold many-body quantum system can be understood as a combination of early time quantum…
Solvable model for a charge- superconductor
Nikolay V. Gnezdilov, Yuxuan Wang
A charge- superconductor forms due to the condensation of quartets of electrons. While in previous works the mechanism for the formation of charge- superconductivity has be…
Ultrafast dynamics of cold Fermi gas after a local quench
N. V. Gnezdilov, A. I. Pavlov, V. Ohanesjan +2
We consider non-equilibrium dynamics of two initially independent reservoirs and filled with a cold Fermi gas coupled and decoupled by two quantum quenches following one an…
Quantum tunneling dynamics in a complex-valued Sachdev-Ye-Kitaev model quench-coupled to a cool bath
Y. Cheipesh, A. I. Pavlov, V. Ohanesjan +2
The Sachdev-Ye-Kitaev (SYK) model describes interacting fermionic zero modes in zero spatial dimensions, e.g. quantum dot, with interactions strong enough to completely washout qua…
Planckian superconductor
Y. Cheipesh, A. I. Pavlov, V. Scopelliti +2
The Planckian relaxation rate sets a characteristic time scale for both equilibration of quantum critical systems and maximal quantum chaos.…
Gapless odd-frequency superconductivity induced by the Sachdev-Ye-Kitaev model

We show that a single-fermion quantum dot acquires odd-frequency Gor'kov anomalous averages in proximity to strongly correlated Majorana zero modes, described by the Sachdev-Ye-Kit…
Low-high voltage duality in tunneling spectroscopy of the Sachdev-Ye-Kitaev model
N. V. Gnezdilov, J. A. Hutasoit, C. W. J. Beenakker
The Sachdev-Ye-Kitaev (SYK) model describes a strongly correlated metal with all-to-all random interactions (average strength ) between fermions (complex Dirac fermions or r…
Valley switch in a graphene superlattice due to pseudo-Andreev reflection
C. W. J. Beenakker, N. V. Gnezdilov, E. Dresselhaus +4
Dirac electrons in graphene have a valley degree of freedom that is being explored as a carrier of information. In that context of "valleytronics" one seeks to coherently manipulat…
First order dipolar phase transition in the Dicke model with infinitely coordinated frustrating interaction
Sergei I. Mukhin, Nikolay V. Gnezdilov
We found analytically a first order quantum phase transition in the Cooper pair box array of low-capacitance Josephson junctions capacitively coupled to a resonant photon in a…
Wiedemann-Franz-type relation between shot noise and thermal conduction of Majorana surface states in a three-dimensional topological superconductor
N. V. Gnezdilov, M. Diez, M. J. Pacholski +1
We compare the thermal conductance (at temperature ) and the electrical shot noise power (at bias voltage ) of Majorana fermi…
Dipolar phase transitions in the cavity with Majorana populated Josephson junctions
S. I. Mukhin, N. V. Gnezdilov, Seid ali Seidov
We found that QED in the lowest eigenstate of the microwave-cavity, capacitively coupled with Majorana populated Josephson junctions array, is described with an effective m…

E. E. Saperstein, M. Baldo, N. V. Gnezdilov +2
Two aspects of the problem of evaluating double odd-even mass differences D_2 in semi-magic nuclei are studied related to existence of two components with different properties, a s…
